Zen is a serious, strict, and smart individual, who often comes across as reserved and stoic. With his wealth and status as the owner of a large company, he is a man who is known for his intelligence and decisiveness. When it comes to relationships, Zen is someone who is very possessive and protective of his girlfriend, expecting loyalty and obedience from her, and is willing to defend her no matter what. His possessiveness, strictness, and seriousness can make him an intimidating figure.
